By current estimates, Southcentral Alaska will have to import LNG or CNG by 2015 to supplement Cook Inlet production.Utilizes diesel for half of electric generation and most space heating needs. Home expenditures now rival the mortgage - especially in the winter.Interior AlaskaRural AlaskaAn Energy Shortage in Alaska - Really?According to state reports, the North Slope has 235 trillion cubic (tcf) of technically recoverable gas. This would supply 5 GW of energy for 1,000 years.

New gas extraction techniques (fracking) have driven the price of natural gas to record lows (~$3/mcf). As fracking becomes more widespread across the world, Alaska’s North Slope gas assets are virtually assured to remain ‘stranded’.How do we use this plentiful source of inexpensive energy for the benefit of all Alaskans?We propose asolution...ALASKA'S ENERGY SOLUTIONHVDC:North Slope Power GenerationEconomies of ScaleCost EffectiveLower EmissionsNew MarketsLarger generation capacity producing more efficient power is more affordableLarger consumer base creates more affordable powerMore environmentally responsible and a step toward sustainabilityTaking stranded gas to market, creating a long-term, sustainable marketLarge-scale natural gas generation on the North SlopeHigh-voltage direct current transmission system designed for delivery of affordable energy at maximum efficiency throughout the stateAbundant, affordable power for:North Slope operationsFairbanks and other Railbelt communitiesRemote mines, military and processorsHeat and power for rural communitieHigh Voltage Direct Current TransmissionReliable & redundant designLocal spinning reserve98% availabilityMost efficient technology for delivery bulk power long distancesMost cost effectiveDouble circuit (bipolar)Maintained locally ensuring reliabilityLower installed costsReduced Right of Way (ROW)HVDC:Connecting the WorldPower
